We analyze the performance of MAC-layer Reed-Solomon error recovery in the CDMA2000 1xEV-DO broadcast and multicast services (BCMCS) environment, with respect to the size of the error control block (ECB) and the air-channel condition, and establish the relationship between ECB size, error-recovery capacity and energy consumption. Real-time traffic, such as voice and video streaming, is very sensitive to delay, but can stand a certain level of packet loss. We therefore propose an energy-efficient size of the ECB to reduce the average energy consumption during error recovery while minimizing the reduction in service quality for real-time multimedia applications. Extensive simulation results suggest that a significant amount of energy can be saved with negligible performance degradation by selecting the appropriate ECB size for the bit error-rate of the forward traffic channel, instead of always choosing the largest possible ECB, with the sole aim of increasing error recovery performance
